The H2n features our best microphones yet and is the only portable recorder with five mic capsules onboard. This design enables the H2n to offer four unique recording modes: Mid-Side (MS) stereo, 90° X/Y stereo, 2-channel and 4-channel surround sound.
The H2n is the first handheld recorder to offer Mid-Side stereo recording, a technique used for many years in film and broadcast, where ambiance and surrounding noise are crucial. Mid-Side recording combines a uni-directional Mid mic that captures sound directly in front of you and a bi-directional Side mic that captures sound from your left and right. By increasing or decreasing the level of the Side mic, you can control the width of the stereo field, which gives you incredible flexibility over your recordings. If you record in RAW mode, you can even adjust the stereo width after recording.
Five built-in mic capsules provide Mid-Side (MS) stereo, 90° X/Y stereo, 2-channel and 4-channel recording modes
